I'm trying to follow along with the video tutorial (Part 1) for
SooperSeekrit. I have my project set up, my database running

to connect to the database and create the user table. Instead I get
a stack trace.
I've gone back and double checked everything, and it all seems
fine. My JDBC driver is in the Library folder, etc. It seems that
the database type isn't being identified somewhere. The stack trace
(bottom of it) is below. I'd appreciate any help!

So, there are a few important things missing from the video tutorial;
when using PostgreSQL, the PostresqlPlugin framework must be added,
and specified. The information to figure this out wasn't present on
the wiki.objectstyle.org web site. It really is a confusing web site
- Confluence doesn't work that well. But I do now have it creating db
objects.
